Safety Precautions:
• Meter should be installed by a qualified electrician.
• Turn off all power supplying the equipment before preforming any
installation or service. Use a volt meter to confirm power is off.
• Use of this device inconsistent with this manual can cause permanent
damage to the unit and/or serious harm to the installer or operator.
Tools/Materials List:
• Volt meter
• Small standard screwdriver
• DIN-Rail
• UL Listed Type 4 Enclosure (with appropriately rated conduit and
fittings) is required if meter will be installed outdoors
Functions:
• Long-term active electricity measuring without adjustment.
• Meets IEC 62053-21 and IEC 62052-11 standards (static AC active meter)
Installation Instructions:
1. Use a volt meter to confirm that you have 120 volts between L1 and
neutral. This meter will not function correctly unless this is the case. If
there are two hot lines and there is 240V between them, you have a
120/240V system. In this case you will use an EKM-25IDS v.2 meter.
2. Disconnect or switch power off before attempting to install, connect,
disconnect, or service the meter. ALL POWER MUST BE TURNED OFF!
3. IMPORTANT: Distinguish and then identify the hot Line and the
neutral line. Label both of them.
4. Once the power has been turned off, pass line 1 through the hole on
the right of the meter and pass the neutral line thought the hole on the
left side of the meter. (for a retrofit installation this may first require
disconnecting L1 and neutral from a breaker or junction box)
5. Once the wires are through the meter the ends should be reconnected
in their original positions. On the meter, tighten down the tap screws
for each line that passes through the meter. The tap screws penetrate
the wire insulation and power the meter once the power is turned on.
6. Mount the meter using 35mm DIN Rail in a protected indoor location.
If installing outdoors, a UL Listed Type 4 Enclosure is required.
7. Once the above steps are completed, and you are ready, you can turn
the power back on and begin to read your meter.
Pulse Output(Fig 2):
• Terminals 1 and 2 are for pulse output. Pulse rate: 800 Impulse/kWh.
Polarity sensitive. Maximum 27VDC, 27mA.
• Red LED on the meter face flashes 800 times/kWh. 1 flash = 1.25Wh.
